Hi Grayh,

Oracle needs some of the kernel parameters needs to be set as per its requirements to work perfectly. So before you install you will have tune all the necessary parameters as per oracle requirements.

All the details will be there in oracle installation guide.

Your installation errors are clearly showing that those kernel values didn't met it's requirement. Tune those as per installation guide and proceed with installation.

Hi
In my experience you must agree to all the check that oracle request, so basically you must change all the given kernel parameters, except for the maxswapchuncks which is missing on newest HPUX release and deal only with maximum amount of configurable swap.

Other parameters deal with process memory allocation, ipc (semaphores, shared memory and message queues) and files: minimum request from oracle must be satisfied, that's all :)

hope it help

Is that a way i can add the above to the Kernel as it is missing.. If so plz give the command

[Cesare Salvioni]

there should be no need for it, really don't know if you can cheat the system making it seems a parameter exists.
Is oracle only warning and complaining or really the installation doesn't work?
In first case DO REALLY NOT WORRY AND GO ON

You can create "forged" kernel tunables to get around these sorts of things using "kctune -u"

kctune -u maxswapchunks=16834

Should do it

Althouh I thought in the Oracle installer you could choose to ignore these warnings and continue anyway

If this is 11iv3, then to set all the other parameters appropriately for Oracle, you could just install Tune-N-Tools from here:

And then just run:

tunserver -o

oops

that should have been:

tuneserver -o

Thanks every one...
